Subject [jira] [Created] (HDFS-10279) Improve the validation for tolerated volumes
Date Tue, 12 Apr 2016 05:35:25 GMT
Lin Yiqun created HDFS-10279:
--------------------------------

             Summary: Improve the validation for tolerated volumes
                 Key: HDFS-10279
                 URL: https://issues.apache.org/jira/browse/HDFS-10279
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Lin Yiqun
            Assignee: Lin Yiqun


Now the misconfiguration for dfs.datanode.failed.volumes.tolerated are detected too late and
not easily be found. We can move the validation logic for tolerated volumes to a eariler time
that before datanode regists to namenode. And this will let us detect the misconfiguration
soon and easily.
